由于項(xiàng)目需要，把項(xiàng)目升級到了php7。但是升級了之后發(fā)現(xiàn)mongo擴(kuò)展不能用了。php7.0以上只支持mongodb擴(kuò)展了。而mongodb擴(kuò)展的驅(qū)動使用起來比monmgo擴(kuò)展顯得很復(fù)雜，啰嗦。在網(wǎng)上找了很久。終于找到了一個比較簡潔的mongodb類。語法跟mongo的差不多。清晰，自然。

項(xiàng)目地址https://github.com/mongodb/mongo-php-library

因?yàn)轫?xiàng)目是國外友人貢獻(xiàn)的。所以沒有可以看的很明白的文檔。這里整理了一些常用的方法。

獲取實(shí)例

$uri = "mongodb://username:password@host/database";
$client = new MongoDBClient($uri);

獲取集合

$collection = $client->selectCollection("test","test");

獲取一條數(shù)據(jù)

$data = $collection->findOne(["id"=>1]);

獲取多條數(shù)據(jù)

$where = ["type"=>1];
$options = array(
    "projection" => array("id" => 1, "age" => 1, "name" => -1), // 指定返回哪些字段 1 表示返回 -1 表示不返回
    "sort" => array("id" => -1), // 指定排序字段
    "limit" => 10, // 指定返回的條數(shù)
    "skip" => 0, // 指定起始位置
);
$data = $collection->find($where,$options)->toArray();
var_dump($data);

去重

$fileName = "name";
$where = ["id" => ["$lt" => 100]]
$ret = $this->collection->distinct($fileName,$where);

插入一條數(shù)據(jù)

$data = array(
    "id" => 2,
    "age" => 20,
    "name" => "張三"
);
$ret = $collection->insertOne($data);
$id=$ret->getInsertedId();

批量插入

$data = array(
    ["id" => 1, "age" => 21, "name" => "1xiaoli"],
    ["id" => 2, "age" => 22, "name" => "2xiaoli"],
    ["id" => 3, "age" => 23, "name" => "3xiaoli"],
    ["id" => 4, "age" => 26, "name" => "4xiaoli"],
    ["id" => 5, "age" => 24, "name" => "5xiaoli"],
    ["id" => 6, "age" => 25, "name" => "6xiaoli"],
);
$ret = $collection->insertMany($data);
# 返回插入id
var_dump($ret->getInsertedIds());

更新一條

$ret = $collection->updateOne(array("id" => 2), array("$set" => array("age" => 56)));

更新多條

$ret = $collection->updateMany(array("id" => ["$gt" => 1]), array("$set" => array("age" => 56, "name" => "x")));

刪除一條

$ret = $collection->deleteOne(array("id" => 2));

刪除多條

$collection->deleteMany(array("id" => array("$in" => array(1, 2))));

聚合

$ops = [
    [
        "$match" =>["type"=>["$in"=>[2,4]]]
    ],
    [
        "$sort" => ["list.create_time" => -1]  //sort順序不能變，否則會造成排序混亂，注意先排序再分頁
    ],
    [
        "$skip" => 0
    ],
    [
        "$limit" => 20000
    ],
];
$data = $collection->aggregate($ops);
foreach ($data as $document)
{
    var_dump($document);
}
